Question
Indicate the number of $\sigma$ and $\pi$ bonds in the molecule $\text{CH}_2=\text{C}=\text{CH}_2.$

Answer
$\ \ \ \ \ \ \ \ {\text{H}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{H}} \\\ \ \ \ \ \ \ \ \ |\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ | \\\ \text{H}-\text{C}=\text{C}=\text{C}-\text{H}$
Number of σ bonds = 6, Number of π bonds = 2
Reason: All single bonds are $\sigma$ bonds. Each double bond has $1\sigma$ and $1\pi$ bond.
